Abstract

Improvements in electronic signal processing apparatus of the type to provide indications of the presence of relatively low energy periodic electrical pulses, characterized in that said apparatus comprise means for supplying said relatively low energy periodic electrical pulses; means for supplying periodic electrical reference pulses; bistable accumulator means having a first input coupled to said low energy pulse supply means, a second input coupled to said reference periodic pulse supply means and an output, at the output of which a first output level is provided during each interval between the appearance of one of said periodic reference pulses and the next low energy pulse and a second output level during each interval between the appearance of said next low energy impulse and the next impulse of said periodic reference pulses ; and averaging detection means, whose input is supplied from the output of said bistable accumulating means and whose output provides said indications.
